基于模型自航试验的自升式平台主机功率估算

Power Estimation of Jack-Up Platform Host Based on Model Self Navigation Test

为确定勘察平台自航所需的主机功率,对自升式平台的缩尺比模型自航试验进行设计,并开展不同航速下平台模型的自航试验。在此基础上,得到螺旋桨推力与平台航行时阻力相等的自航点,并计算实际平台在不同航速下所需的主机功率。研究成果可为自升式勘察平台设计过程中的主机功率选择提供一定参考。

To determine the required main engine power for self navigation of the survey platform,a scaled model self navigation test of the self elevating platform is designed,and self navigation tests of the platform model are carried out at different speeds.On this basis,the model propulsion point where the propeller thrust is equal to the resistance of the platform during navigation is obtained,and the actual engine power required for the platform at different speeds is calculated.The research results can provide some references for the selection of host power in the design process of jack-up survey platforms.
